The only errors that I can spot are:
1. You are not providing the member values to the constructor while instantiating the obj object.
2. In your display function the parameters are not being read from the file. The existing parameters of that particular object are being outputted.

facing "fatal error C1004: unexpected end of file found"

I am assuming that now you are able to compile your program.

After writing to the file, you need to flush out the buffer and close the file.

outFile << std::flush;
outFile.close();


After reading input also you need to close the file.

indentation is terrible, but it looks like you ain't put a ";" at the end of your class declaration.
